There is no such place as South River Plains on The Sims 2 Castaway, you are thinking of South River Jungle. :)
the chasm is on the second island in the west river plains.
You find sisal on the second and third islands. To be specific: 2nd Island: Skull Rock Jungle, West River Plains, East Rivers Plains, South River Jungle, Pirates Cove, Hidden Lagoon 3rd Island: Volcano Jungle, Ancient Theater, North Volcano Jungle, Geyser Plains, Volcano Summit
First of you need to craft a stone axe. Then you need to find Koa trees found in Ancient Theatre, Volcano Jungle, West River Plains Skull Rock Jungle and Airplane Jungle. Or find Teak trees found in Volcano Overlook, and Volcano Jungle.
I think you have to be at either east river plains or west river plains to do it firstly you need the airplane radio and the thing that looks like a sky TV dish then you repair the radio scroll up on the selection bar thingy and find send SOS and this blue circle should rise up getting bigger as it goes and if you her the little music thing(ding ding ding ding, ding ding, doon)and a rectangle appears at the top of the screen saying send SOS from high ground:done you should have done it
